My invention relates to improvements in apparatus for deterging radiators or the like, and has for an important object thereof the provision of an apparatus of such character that the 5 deterging may be done under conditions wherein the radiator is submerged in a detergent solution and said solution heated and circulated through the radiator.

Another object of my invention is to provide an apparatus of the above described character which is simple in construction, durable in use, elcient in operation, andeconomical in manufacture. Y

A further object of my invention is to provid an apparatus of the above described character so constructed and arranged as to accommodate radiators of different sizes.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawings. Y

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Figure 1 is a longitudinal sectional view of my invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken substantially on the line 3 3 of Figure 1, certain of the parts being illustrated partly in elevation.

Figure 4 is a detail sectional view of the sediment trap taken on the line 4-4 of Figure 1.

Figure 5 is a fragmentary end elevation of the lower end of the chimney construction illustrating the latter in connected relation with the ilues.

In practicing my invention I provide a tank 5 supported on the upper faces of the walls 6 of a iire-box construction 1, one of said walls being provided with a door 8.

The tank is fashioned with side, front, and rear walls I and I I respectively and formed with a closed bottom I2 and an inwardly flanged top I3 defining an opening covered by a lid I4 hinged to said top.

Secured to the bottom I2, adjacent the front wall I0 and subjacent said bottom is a transversely extending boiler or cylindrical shaped heating chamber I5, the ends I6 of which are closed and extend laterally of the side walls 9. Secured to the lower peripheral face of the boiler I are a plurality of inclined tubes Il having communication with the boiler and extending upwardly and rearwardly therefrom. The rear ends of the tubes I] are angularly disposed and extend vertically through the bottom I2 and are provided with inclined upper and outer faces Ila. A substantially V-shaped guard transverses the bottom of the tank and serves as a cover for the angularly disposed open ends of the tubes I1, 5 the apex of said guard being disposed above the faces I1 and the upper and lower edges of the faces engaging the inner inclined faces of the guard to permit circulation of liquid from the tank into the tubes I 1. The lower ends of the 10 guard I8 are disposed above the bottom I2 of the tank as clearly illustrated in Figure 1.

Extending vertically through the tank are a plurality of iiues I9, the lower ends of which communicate with the fire-box 1 and the upper 15 ends connected to the lower trifurcated ends of a chimney 20 whereby gases, smoke, or the like, are vrelieved from the fire-box. Transversing the tank 5 adjacent the front wall I0 and spaced below the top I3 is a hollow cylindrical shaped 20 valve member 2I, the outer ends of which extend beyond the side walls I0 and have communication with the boiler 5 by means of conduits 22, and said valve member-2l is formed with a tierce of a line discharged ports 23. i

Rotatably mounted on the valve member 2| is a valve sleeve 24 transversing the interior of the tank between the side walls 9, and said sleeve is provided with a tierce of outlet pipes 25 adapted .for registry with the ports 23 to permit discharge 30 of liquid from the valve member -into the tank when in registry with the ports 23. The sleeve 24 is also provided with a pipe section 26 adapted for registry with the intermediate port 23 of the tierce supports when the sleeve has been ro- 35 tated to close communication between the ports 23 and pipes 25, as clearly illustrated in Figure 1 of the drawings. One end of the sleeve 24 is provided with a laterally extending arm 21 having pivoted thereto the lower end of a sleeve operat- 40 ing handle 28, the upper section of which extends through a slot formed in the ange top I3 laterally of the lid I4, and said upper section is provided with a handle grip 29 whereby to raise and lower the handle 28 and thus rotate the 45 sleeve 24 in selected positions with the pipe 25 and pipe section 26.

Secured to the wall III and top I3, and centrally of the wall and top, is a U-shaped bracket 30 for accommodating the upper end of an in- 5o clined supporting rod 3| disposed longitudinally of the tank. The lower end of the rod I is mounted within a similar shaped bracket 32 secured to the intermediate ue I9, as illustrated in Figure 1 of the drawings.

-535 is provided with the usual outlet and inlet connections 36 and 31 in the lower and upper ends thereof respectively together with the filler connection 38 in said upper end. The outlet connection 36 of said radiator is detachably connected by means of a exible conduit 39 to the pipe connection 26 and the inlet connection 31 is disposed above the level L of a detergent solution S contained inthe tank and the connection 38 together with the radiator 35 maintained submerged in said solutions. The bottom I2 of the tank adjacent the front wall I0 and to one side thereof is fashioned with a depending sediment trap 40 equipped with aclean-out opening closed by a plug 4|, and said trap is adapted to accumulate foreign matter therein for subsequent removal therefrom upon removal of the plug 4|.

In operation, a radiator is positioned upon the plate 34 and the tank lled with a suitable detergent-solution, the level of said solution being disposed above the upper face of the radiator and below the port of the connection 31 and said radiator is connected by means of the conduit 39 to the pipe connection 26 of the sleeve.

When the radiator is thus positioned within the ltank, the sleeve is operated to eiect communication between the pipes 5 and interior of the valve member 2D through the ports 23 and the "boiler is operated, through the medium of a suitable source of heat energy within the lire-box 1, to heat the solution within the boiler thereby causing a circulation of said solution upwardly through the conduits 22, into the valve member 2|, out into the tank through the pipes 25 and 40 returned to the boiler I5 through the tubes I1.

When the solution has been suiciently heated, the sleeve 24 is operated by the handle 28 to effect communication between the interior of the valve 2| and the conduit 39 thereby causing the solution to be circulated through the coils of the radiator and discharged through the connection 38, the connection 31 serving to permit entrance of air to the radiator to eiect a free iiow oi the solution therethrough. Obviously,

as a heated solution is circulatedthrough the radiator, it serves to cleanse and purge the radiator of foreign matter and the like.

' Upon completion of the cleansing operation, the lid is'raised, and the iiexible connection 9 detached from the radiator to permit removal ofthe radiator from the tank. 'I'he ends of the boiler I6 in' the lower sections thereof are fashioned with clean-out ports closed by plugs |6a whereby said boiler may be readily cleaned or the ta'nk drained of the solution therein. It being also noted that removal of the plug 4| of the trap 40 will also function to drain ,the tank.

From the foregoing it will be apparent that I have provided a simple and elcient apparatus for deterging radiators, and while I have described the apparatus as being utilized in connection with deterging automotive radiators, it is to be distinctly understood that other type radiators may be introduced Within the tank for cleaning and likewise similar articles.

What is claimed is:

1. An apparatus of the class described, comprising, a tank, a rotatable valve unit within said tank, means having communication with said tank and unit for heating and circulating a solution through said tank and unit, a support carried by said tank and adapted to support a radiator within the solution contained within the tank, said valve unit provided with an outlet port adapted for communication with said radiator to eiect circulation oi' the solution through the latter from said means, said valve unit formed with discharge ports communicating with the interior of the tank for circulating said solution from said means about said radiator and through said tank, and means connected to said unit for controlling'said ports to selectively circulate said solution through and about said radiator.

2. Anapparatus of the class described, comprising, a tank, a rotatable valve unit within said tank, means having communication with said tank and unit for heating and circulating a solution through said tank and unit, a support carried by said tank and adapted to support a radiator within the solution contained within the tank, said valve unit provided with an outlet port I adapted for communication with said radiator to effect circulation of the solution through the latter from said means, said valve unit formed with discharge ports communicating with the in-v terior of the tank for circulating said solution from said means about said radiator and through said tank, and a handle connected to said valve unit and extending without said tank for operating said valve unit in a manner to effect selective circulation of said solution through and about said radiator.
